For all the pros out there, would you be concerned when a system that produced 20% profit a month suddenly dropped to only 15%?
If you'd like to hear more from Steven Goldstein, the youtube channel UKspreadbetting did an interview with him a while ago, here's the link for the playlist:
Strange that you called James Simons a loser. He has the best long-term track record among hedge fund managers. What I didn't like about Renaissance Technologies is that they keep the best fund to employees only. How can his investors know for sure their best fund does not trade against their other funds? Employees do have some incentives to make sure their own money does best.

Strange that you took what I wrote in 1st degree, it was just an ironic reply to the previous poster's claim all algorithmic traders go bust (or similar)
Would you be concerned when a system that produced 20% profit a month suddenly dropped to only 15%? No - because if those kind of returns could be sustainable you would be one of the richest people on the planet.
